The average toilet uses 1.6 gallons of water per flush. In a household with four people, that’s about 21 gallons of water used per day just from flushing the toilet! And that’s not even including all the other ways we use water throughout the day, like brushing our teeth, taking showers, and doing laundry.
Just think about how much water is wasted every day when we leave the faucet running while we brush our teeth or do dishes. All of this wasted water adds up, and it takes a toll on our environment and our wallets.
If you’re like most people, you probably don’t think much about how much water your toilet uses each time you flush. But the truth is, toilets can use a lot of water – as much as 6 gallons per flush! That adds up to a lot of water over the course of a year, especially if you have a family.
There are ways to reduce the amount of water your toilet uses, though. One is to install a low-flow toilet, which uses less water per flush. You can also add a brick or two to your toilet’s tank to reduce the amount of water it holds and thus the amount that is used each time you flush.
Finally, be sure to only flush when necessary – things like tissue paper and small pieces of garbage can usually be disposed of in other ways.
By taking these simple steps, you can help conserve water and save money on your utility bills. So think twice before you flush!
How Much Water Does a Toilet Use Per Day
It’s no secret that toilets use a lot of water. In fact, toilets are responsible for about 30% of all indoor water usage. But just how much water does a toilet use per day?
The answer may surprise you. A typical toilet uses about 3-5 gallons of water per flush. That means that if you flush your toilet 10 times per day, you’re using 30-50 gallons of water just for flushing!
Of course, there are ways to reduce the amount of water your toilet uses. Low-flow toilets can save you up to 1 gallon per flush, and dual-flush toilets can save even more. If you’re really looking to conserve water, consider installing a composting toilet which doesn’t require any water at all.
No matter what type of toilet you have, it’s important to be mindful of your water usage. Just a few small changes can make a big difference in the long run!

That’s a lot of water saved, just by not flushing the toilet!

Do Toilets Use More Water Than Showers?
The average person uses approximately 50 gallons of water per day. Of that, about 2.5 gallons is used for drinking and cooking, while the remaining 47.5 gallons are used for other activities such as bathing, laundry, flushing the toilet, and watering plants [1].
Toilets are one of the biggest water users in the home, accounting for nearly 30% of indoor water usage [2].
The average toilet uses 1.6 gallons per flush (gpf), but newer toilets can use as little as 1.28 gpf or less. Compare this to a shower which uses an average of 2.1 gallons per minute (gpm). So if you take a 10-minute shower, you’re using 21 gallons of water; whereas if you flush the toilet 5 times throughout the day, you’re only using 8 gallons of water total.
So even though toilets use less water per flush than showers use per minute, they are still responsible for more overall water usage in the home because they are used more frequently than showers throughout the day. You can save even more water by retrofitting your toilets with low-flush or dual-flush models – some estimates say this can save up to 20% on your indoor water usage [3].
